schliz writes: Australian data centre and telecommunications provider Vocus has installed two new underwater fibre links across the Sydney Harbour in a bid for the lowest connection latency between the city's financial district and the Australian Securities Exchange's recently opened data centre, north of the CBD. The project involved 1.6 kilometres of custom, 312-core single-mode optical fibre cable, and was expected to deliver a route that is 400 metres shorter than existing links.
